When it comes to salmon, there are three main types: King, Sockeye, and Coho. But what’s the difference between them? In this blog post, we compare the three popular salmon types—King, Sockeye, and Coho—so you can make an informed decision when shopping for salmon.
Overview About King Salmon
King Salmon, also known as the Chinook Salmon, is one of the most sought-after fish in Alaska. Native to the Pacific coast of North America, this species is the largest of all Pacific salmon and can reach over 100 pounds. It is distinguished by its silver-colored body, dense, meaty texture, rich fatty consistency, and full fresh fish flavor with a hint of sweetness. Its life cycle begins with spawning in relatively deep and fast-moving freshwater rivers.
In Alaska, King salmon eggs generally hatch in early spring, and the young fish remain fresh until they are ready to migrate to the ocean in search of food. The average King Salmon can measure over 36 inches in length and weigh up to 30 pounds. This species is the official state fish of Alaska, and its popularity has made it a symbol of healthy fisheries throughout the region.
Overview About Coho Salmon
Coho salmon (Oncorhynchus kisutch) is a species of anadromous fish in the salmon family and one of the five Pacific salmon species. They are medium to large in size, with adults typically weighing 8 to 12 pounds and measuring 24 to 30 inches long, though some individuals have been recorded weighing up to 31 pounds. Coho salmon have silvery sides and metallic blue backs with irregular black spots.
Spawning males have bright red sides and bright green heads. Throughout the year, their appearance can change depending on whether they are breeding or not. This species of salmon is considered to be the “in-between” size—not too big but not too small—which makes them a popular choice among anglers looking for a good catch.
Overview About Sockeye Salmon
Sockeye Salmon, also known as red or blueback salmon, is a Pacific salmon native to the North Pacific. They are relatively small, measuring 18 to 31 inches in length and weighing 4-15 pounds. These fish have a distinct metallic blue-green back and silver sides, and during spawning, they have an intense reddish hue.
Sockeye salmon are social fish who swim in runs and form social hierarchies while making their way to mating grounds. They are highly prized for their succulent, bright-orange meat, rich in texture and flavor. For those that love salmon, sockeye tastes the most like traditional salmon.
Nutritional Comparison of King, Coho, and Sockeye Salmon
Comparing the nutritional content of different types of salmon can take time and effort. Whether you’re trying to decide which salmon to buy or want to know more about the health benefits of each type, this guide will help you navigate the differences between King, Coho, and Sockeye salmon.
King Salmon is one of the most sought-after types of wild salmon. It has a rich, buttery flavor and high levels of heart-healthy omega-3 fatty acids. Nutritionally, King Salmon has fewer calories than Sockeye Salmon, but it has lower protein and higher levels of sodium and calcium.
Sockeye Salmon is one of the best-tasting (and healthiest) types of salmon with a medium fat content. It has fewer calories and less fat than King Salmon but more protein. Regarding vitamins and minerals, sockeye salmon is higher in Vitamin B12 than King and Coho Salmon.
Coho Salmon is slightly lower in calories than sockeye salmon and higher in protein content. Nutritionally it falls somewhere between King and Sockeye Salmon with moderate amounts of heart-healthy omega-3 fatty acids and vitamins like Vitamin B12. Coho also has a milder flavor than both King Salmon and Sockeye Salmon.
Ultimately, deciding which type of salmon to buy depends on your personal preferences for taste, texture, budget, and nutritional needs. Wild-caught salmon will always be the best option for both nutrition and sustainability reasons. If you’re looking for a type with a milder flavor, Coho may be the best choice for you. If you’re looking for something with less fat but more protein, sockeye may be your better option. And if you’re looking for a richer flavor with higher levels of healthy fats, then king salmon is your best bet!
Taste Difference Between King, Coho, and Sockeye Salmon
Trying to decide between King, Coho, and Sockeye salmon? Here’s what you need to know about the taste difference between these three types of wild Pacific salmon.
King Salmon (Chinook) is the fattiest of the three varieties, with a strong fishy flavor and buttery texture. It’s great for those who like a richer flavor in their fish.
Sockeye Salmon (Red) is the slimmest of the three, so it has a lower fat content than King and Coho salmon. Its bold flavor makes it a great choice for those looking for a stronger taste.
Coho Salmon has a milder flavor than both King Salmon and Sockeye, making it a great “starter” salmon for picky seafood eaters. It also has smaller scales than sockeye, and its meat is pinker than sockeye. Its medium-fat content gives it an enjoyable flavor without being too overpowering.
No matter the type of wild Pacific salmon you choose, you will surely enjoy its delicious flavor!
Differences in Color, Texture, and Size Between King, Coho, and Sockeye Salmon
Are you trying to decide between King, Coho, and Sockeye salmon? You’re not alone! With their differences in color, texture, and size, it cannot be easy to know which type of salmon to choose. To help you make the perfect decision, here is a guide on differentiating between the three types of salmon.
Regarding color, sockeye, Coho, and king salmon have the deepest orange color. On the other hand, pink and chum salmon are generally much lighter. Regarding texture, sockeye salmon has a delicate, large-flakey meat, while Coho has a milder taste and is often considered a “starter salmon” for picky seafood eaters. In terms of size, king salmon is usually the largest of the three types, while Coho is the slimmest with a lower fat content.
When choosing between King, Coho, and Sockeye salmon for your next meal or recipe, consider their differences in color, texture, and size. Sockeye has deep red or marbled flesh with a firm texture that many consider the best type of salmon for flavor. Coho has a milder taste, while the king is usually larger but has a stronger taste than sockeye. Additionally, farmed Atlantic salmon may also be available at some retailers. With this guide in mind, you can decide which type of salmon is ideal for your needs!
Differences in Habitat and Diet Between King, Coho, and Sockeye Salmon
When it comes to different species of salmon, there are three that stand out: King, Coho, and Sockeye. Each of these fish has its own unique habitat and diet.
King salmon can be found on the Pacific Coast from Alaska to California and also in the eastern North Pacific. They tend to inhabit cold, deep waters near the coast and in large rivers. Diet-wise, King salmon feed on smaller fish, crustaceans, and squid.
Coho salmon are found in the eastern North Pacific from Alaska to California. They tend to inhabit shallow coastal areas with various habitats, such as estuaries, creeks, and large rivers. They feed primarily on crustaceans and plankton, which give them darker red-colored meat than other species.
You can find sockeye salmon in the Atlantic Ocean, the western North Pacific Ocean, and many freshwater rivers across North America. In addition to small fish, sockeye eats aquatic insect larvae and plankton in the ocean and adult insects when living in freshwater habitats.
Understanding each species’ unique habitat and diet is essential for those wishing to catch or learn more about them. Knowing where they live and what they eat is key to getting a successful catch or understanding their behavior better.

How to Cook King, Coho, and Sockeye Salmon?
Cooking different types of salmon can be an easy and delicious way to enjoy a seafood dinner. The best way to cook King salmon is on the grill. Start by greasing your grill and heating it. Place the King salmon skin side down on the grill and cook for 3-5 minutes. Check the fish after 8 minutes and keep grilling until you see the sides of the fish start to get opaque and flake easily when tested with a fork. King salmon can be up to 2 inches thick, so allow for 10 minutes per inch.
Coho or Sockeye salmon can be cooked in a cast-iron skillet on the stovetop or poached in fish stock or wine for a more delicate flavor. To cook in a skillet, grease it and heat it over medium-high heat. Place your Coho or Sockeye salmon on a work surface, then place it in the skillet and cook for about 10 minutes per inch of thickness. Turning is not necessary as they will cook evenly on both sides. Start checking the fish after 8 minutes, when you will see the sides of the fish start to get opaque and flake easily when tested with a fork. Coho and sockeye will rarely be thicker than one inch.
Finally, you can also steam your salmon for an even more delicate flavor. To do this, preheat your oven to 375°F, then place your salmon on parchment paper in a baking dish. Cook for 15 minutes and enjoy steamed salmon that’s been cooked to aromatic perfection!
FAQS about King vs. Sockeye vs. Coho
Is Coho More Expensive than Sockeye?
Generally speaking, Coho salmon tends to be more expensive than Sockeye salmon. This is because Coho salmon is a smaller fish and therefore yields less fillet per fish.
